LaMujer:
Good day everyone.


I have an offer to buy one of two inverters.

5kva, 24V
3.5kva, 48V


Both are used, and no batteries.

Which do you advise I buy? I don't have much load, nor do I intend to use any heavy load on it besides basic appliances vis a vis fan, phones, laptop and TV occasionally.


The 3.5kva is a Cruze sine wave, while the 5kva is a stabimatic PSW.

I'm just starting my entry into renewable energy, and although I've read a lot, I haven't practiced anything


I'm also very funds cautious, as the funds no dey ground. Kindly advise

The price difference btw tubular and lithium is getting closer esp if u patronize ppl here who couple such as Valto and isangjohnson. You also get longer cycles with lithium than tubular so dont be pennywise

LaMujer:




Oh yes, I know lithium or lifepo is the best battery bet I can use. But I also know I can't afford it right now. I would have to make do with the less expensive tubular ones

Tubular is a waste of money in 2024.

Honestly this is what I feel too. Original Tubular is around 350k+.

isangjohnson:
1.280m Installation.
12v 2kva/1.6kva hybrid inverter with 80a Mppt, 450v max Voc and Mppt voltage range of 50-430Vdc.
6pcs of 180w pv.
12v 160Ah LFP battery.

wat is the brand of this inverter

My best friend's father is the one selling. It's not being used, and from what pictures I took yesterday on seeing it, I understood why it's going for such price

Not that I don't know better, but you know that situation you are when you know what to do, but don't want to do it? Yeah, that's where I am.


Anyway, thanks. Even though no be wetin I wan hear, but it's the truth nonetheless. I really appreciate. I'd look into getting the lithium, because I also know it means not having to bother about batteries for the next 3-4 years

Better do and live with 100ah LifePO4 than fake 220ah ( DOD 110ah) on a condition that it is truly 220ah. Spend wisely!

Idle consumption is a drawback

The fact that it hasn't been used for a long while? Will it get back to optimal capacity after usage for a while? Or it's gone?

Understood, really sunk in. Thanks.


Obviously, I'm assuming, the 5kva batteries would cost lesser than the 3.5kva, right?

Idle consumption is the power consumed without any load.

Got it, read on it now, thanks

Sorry for the sad experience. I usually call or chat them to confirm availability before placing orders.

You can also explore other options like Longi from Solarco in Abuja (Mr. Fadi is a very helpful and reasonable person).

Pls can i get the contact of solarco/Mr Fadi, i intend purchasing some units..

Person don bring BYD HAN electric vehicle to abuja.. The dealer also have the Avatr 11.

Professionals in the house, what could be the cause of this...

Please assist

Please house, guide me on what I need for this installation.

I only have a 12v 1500W pure sine wave transformer based inverter. I will need a system that can carry fridge in the day on minimum budget.

I plan to buy an 100ah or 172ah Lifepo4 battery.

Please recommend what I need to make this work. Panel, controller, type of wire, .... I want to buy everything and then call an installer.

I won't choose any of the above if I had a choice. They are transformer based which means high idle current use and also the need to get an external charge controller for solar. If i had a gun to my head though, I'd take the 3.5kva48v sha rather than the 5kva24v system cos of efficiency though means getting a 48v system which is almost double a 24v battery system price

Experts in the house, kindly proffer your advice concerning my inverter setup.

I have a 3.5kva SMK Inverter with two pieces of Cworth Energy 2.5kw Lithium 24V batteries (as seen below) and four 380w PV panels. On Wednesday afternoon, the inverter let out two loud sparks and started displaying error code 09 (this would be the second time within three months). A technician suggested that the inverter may not be compatible with the lithium batteries and suggested I replace it with a 3kva Felicity
brand.

Does anyone have an idea on which inverter brand will be most compatible with the batteries?

Thank you.

Sure you're not dealing with a bad wiring issue? No reason why that inverter wouldn't be "compatible" with the batteries.

What is your bulk absorption voltage set as, I think one of the battery cells reached a high voltage thereby triggering the high voltage disconnect which caused the bms to shut down the battery thus damaging the inverter. Solution is to reduce your absorption voltage.
On a second thought, what did your installer state as the cause?

Meant price wise. Edited already boss

What does error code 9 mean from the manual?

Who can say much about this inverter

Can't go wrong with Growatt.

Don't think that's true either. Prices are identical, maybe just 20-30% more expensive for 48v.

I may have to confirm the bulk absorption rate from the installer. After checking the inverter, he stated that he has contacted the manufacturer and would provide an update when they revert to him. The last time it happened, he sent the device to the service center in Lagos (from Abuja) and it was fixed FOC as it was still under warranty. Now that it has recurred, I'm not comfortable using it henceforth.

Error code 09 means "Bus Soft Start Failed"

Please capacity of solar panels required and the charge controller?

HeavenlyBang:

I also thought compatibility shouldn't be an issue but who am I to argue with a professional? Reason I decided to seek expert help here

Disco01:

Depending on ur usage a 700w 350w *2 should be enough for solar panels

For charge controller I recommend powmr mppt 60amps this would give room for possible expansion
